Yup. This game has the foundation of being something desperately needed in the H world, a school life simulator that's not just on rails visual novel or Koikatsu. But the sheer number of bugs is rotting that foundation and though good in it's on right, makes for a unpleasant experience.

it is a great game, and very much reminds me of HHS+ (Hentai High School +, an amazing game, and sounds like just what you wanted) and would not be surprised if it was heavily inspired from it.
an open world, randomly generated characters, and a main thing to manage (being the head master in that case) that helps you do many other stuff, each character being a romance option, story lines attached to specific characters.
and I'm not sure if this game has it, since i haven't reached far into the game, but the ability to make the school and the world much more sexually open.
but i will give it to this game, the graphics are better, and i think it has better promise, at least if it also grows to have mod support.
